Newman Bbrothers organ

I know nothing about these things, it has delicate, thin wood thatmakes a design on the front of the organ, below the keys, not sure what the design is supposed to be, but at a glance it looks like some of it are cut in the shape of leaves. There are knobs lined up behind the keys with writing on them (ect: echo horn, celeste). There are 11 of them and they can be pulled out or pushed in. Newman Bros is on one side of the keys and Chicago Ill is on the other side. The pedals have an N on one and a B on the other. All of the writing appears to be Old English or something close. The pedals also have design around the edges of them. There are decorative wood peices on both sides of the top of the organ. It has a cover that comes down to cover the keys. I am not sure why, but the organ is not working. There is some wear in the stain on some of the edges, but not terrible,  Please tell me what you can with the information I have given. My camera is missing so I will try to send pics later, but please help some if possible for now. Thank you.
